The-- pipe and after performing certain opera- ,condnctors 4f form part of the high tensior tions preliminiiy' to blowing, to come to circuit 5 which contains 'the secondary 6 of i l5 rest and prorinled with :in automatic con transformen G, the'primary 6b of which is 70 troller in the form of n thermal element, in circuit 'with a Suitable interruptor 6 which upon the elongation ot the gather to whereby ai .high tension alternating cnrrent he proper extent, restarts the machine for will be set up vin the circuit 5 .when the ,rethe purposes of blowinghmolding and the sistnn'ce between the conductors 4U of the subsequent operations-w electrode is s uiiiciently reduced permitl the 75 My present invention relates to another spare 'to junipcfrom one t0 the other. This form of automat ic controller and one whosej` occursrwhen ,the descending gather is in close action is due to the fact that the, descending proximity tothe electrodes, at which.r time gather at the proper time forms a part of anthe. gather completes the path of 'thel Spark,

The two poles 8*? of an electro-magnet incontact with the glass Without injuring 8 project int-o the valve chamber above the 85 the bulb blown. and the circuit is therefore ballvvalve, thevsaid magnet being energized `4cnc of high tension. .ln order to permit the, b y coils 8b, whose circuit 9 includes a suitable energy in this circuit to be ns small as pos` source of current (not s own), an electri;u sible, it is in eiiect onlyy a `pilot 'circuit which cally actuated contactmalccr in the forrnof 5 controls an electric contact maker in the an armature 9a and a mechanically actuated 90 circuit of'an ai;` vulve, such as' described in circuit breaker` 9* hai/inginspring pressed my other aigiplication. y movablemember"9, therend of which pr My invention consists further in the -conjects into the path'of the movable frame.

llViththis construction it. will be seen that when the gather in its elongation'has' per' mitted `the high tension current to pass through the circuit of the secondary of the transformer and to temporarily energize the magnet 14 contained therein, a current is permitted to temporarily pass through the circuit tE) and the magnet 8' is caused to 'lift the ball valve from its seat, whereby air under pressure will be admitted through thc outlet port 7c to the tubular piston l0 a'nd actinf upon the closed forward end of the cylinder 1I to shove the sliding head 3 forwardly. This movement of the head will bring one of. the pinsl into contact With the arm 13 of the air valve. and open the latter 4to admit air to start the operation ot the machine. As the air pressure controlled by the valve 7 may be. quite heavy a temporary closure` ofthe circuit 9 will under ordinary' conditions be sufficient to admit sufficient aitocause the sliding head to complete its movement andf` this temporary closure effected by the electro-magnet 14 as 'before described. To insure lhowever that the circuit 9 shall bel broken upon the compltion of the movement of the sliding .trame the contact breaker 9b is provided, the

movablemember 9C of which is moved'to open the circuit ofthe air valve before the frame completes its .forward movement, winch forward movement removes the elecprox-nmty to the descending trodes from. gatherl and further permits the escape of the air, which hasvbceii admitted to Athe cylinder' 11 vthrough the valve 7., tliroughtheport 1l" in the cylinder. The blowing having been performed and the molds opened theI sliding ,frame is returned to' normal position by the gather vfor putting into` operation 'glass` blowing'or molding mechanisms, as such aforesaid applicationv #678231, to which the` .claims-in this are subsidi ary.

Having thus described my invention, what 1I claim and desire to secure by Letters APatent is: v

In a gather actuated controllingpdevice for glass blowing machines, the combination" .with two electrodes having a `gap between them, and located adjacent to the path ofthe descending gather, means tor creating a difference 4ofpotential in the electrodes and means controlled by' a current passing throught-he electrodes fr controllimgr the movement of the blowing machine.

. 2. In a gather actuated 'controlling device. for glass blowing machines, the combination with a liigh tension circuit haring a gai in proximity to the path of the dcsccmliug gather, and n'ieans contained `in the said circuit for coi'itrolling the nliovcmcnt of the blowing machine.y

. In a `gather actuated controlling' device V for glass blowing machines, the combination IWith-albigh tension circuit having a. gap in proximity to the path of the .lescei'nlingr gather, a second circuit controlling thev blow-- ing machine and controlled by the first 'named circuit.

4. In a gather actuated controlling 'device -for glassblowing,Y machines, the combination.

with a source of high tension current,Jcon

,nections therefrom whereby the gather in its-elongation becomes a. part of the circuit from said source, an 'electroirespons'ive means contained in the said connect-ions between the source-and gather and energizing a controlling element of the blowing machine. 5. 1n a gather actuated controlling device for glass blowing machines, tlie combina.'-
